This guide, produced by the City of Paris Urban Planning Department, aims to help project developers integrate environmental issues into their projects right from the design phase, in application of the rules of the bioclimatic Local Urban Plan (PLUb).

It is divided into 3 chapters, each combining extracts from the regulations and practical information sheets:

1 - Environmental performance of new buildings

  • Bioclimatic design and energy requirements
  • Summer comfort and cooling
  • Carbon
  • Renewable energies 
  • Focus: the obligation to connect to the heating network
  • Focus: the biosolar roof
  • Specific recommendations (overhangs, offices) 

2 - Environmental performance of existing buildings

  • Thermal and energy performance
  • Focus: Heritage protection and the opinion of Architectes des Bâtiments de France
  • Materials
  • Focus: Thermal performance of materials used in renovation 
  • Facades
  • Roofs
  • Focus: The sarking method
  • Gable walls
  • Renewable energies 
  • Summer comfort

3 - Revegetation of open spaces and buildings

  • Localized and sectorized rules 
  • Focus: qualifying spaces
  • Existing ecological qualities
  • Designing open spaces
  • Revegetation of buildings
  • Focus: Urban agriculture


To help petitioners understand the rules and how to translate them into concrete projects, and to better prepare their authorization applications, the Apur also provides a spreadsheet to automate calculations of the quantitative regulatory requirements of article UG4 of the PLU.
